An important object of the invention is to provide a rudder tiller vlock which is especially adapted for use on lifeboats and boats of like capacity and design which in an emergency will permit the applicationl of a tiller to the usual rud- Y derquickly and eiectively.

Other objects and advantages of the invention will become apparent to the reader of the iollowing description.

In the drawings: Figure 1 represents a fragmentary side elevational view showing the tiller lock, tiller and upper portion of a rudder.

Figure 2 is a fragmentary top plan view of the structure shown in Figure 1. v

Figure 4 is a front elevational view Vof the lock. n

- ure 1 at its forward edge, this latter edge being denoted by numeral 1. l

Numeral 8 generally refers to .an improved lock for disposition against the curved surface l.

-A tiller isdenoted by numeral 9 and has a slot therein for receiving the upper portion of the rudder 5, this tiller having a bulge for disposition in the notch 6 as the tiller fits snugly over the upper portion of the rudder. v

Thelock 8 consists of -an elongated arcuateshaped plate I Il secured on and adapted to lie ilatly against the curved portion 'I of the rudder, the lower portion of this platey I0 having an ofi'` `set II into which the head I2 of a lock element xment I3 to overcomethe spring I6, the head I2 may be pushed 'into the oiset II and the tiller 9 can then easily be removed.

Obviously, the tiller can be slipped downv over the upper portion of the rudder 5 as shown in Figure 1 and will simply slide over the lock mechanism without any manua1 actuation thereof.

2. In combination, a rudder, a tiller for the rudder, and a quick operative latch for holding the tiller to the rudder, said latch consisting of a plate, the upper portion of the rudder being gradually reduced, said plate being disposed against the reduced portion of the rudder, a spring projected movable member having a head adapted to abut a tiller, said plate having an oiset therein for receiving the head when the vmember is in depressed position. y

3. In combination, a rudder, a tiller for the rudder, and a quick operative latch for holding the tiller to the rudder, said latch consisting of a plate, the upper portion of the rudder being gradually reduced, said plate being disposed against the reduced portion of the rudder, a spring projected movable member having a head adaptedvto abut a tiller, said plate having an 01T- set therein for receiving the head when the member is in depressed position, said member being provided with outwardly movable stop means.
